Patented June 17, 1930 UNITED STATES PATENTQOFFICE AnnR :r. MEYER, F DETROIT, MICHIGAN, assIGNoR To CONTINENTAL IoToRs CORPORATION, OF DETROIT, MICHIGAN, A cORrORATIoN or VIRGINIA INTERNAL-COMBUSTION ENGINE Application filed August 6, 1928. Serial NO. 297,779.

' cylinders as distinguished from engines hav ing cylinders cast as a unit with the cylinder block. In the former type difficulty has been experienced in satisfactorily jacketing the cylinders for cooling and at the same time preventing leakage of the cooling fluid from the jacket into the engine crank case resulting in oil dilution, inefficiency, and damage to the engine.

Referring to the accompanying drawings 7 in which I have illustrated one embodiment of my invention,

Fig. 1 is a sectional elevation view through a typical engine cylinder and associated jacketing structure, along 11 of Fig. 2,

Fig. 2 is a sectional plan view along 2-2 of Fig. 1, and

Figs. 3 and 4 are detail views through 3-3 and 1- 1 respectively of Fig. 2.

In the drawings the engine comprises a cylinder block casting A and a crank case B formed integrally with the cylinder block A or separately therefrom as desired. In

the drawings these parts are illustrated as a single castmg.

The cylinder block A receives spaced cylinders G, the engine comprising one or more cylinders as will be understood. Cylinders C accommodate the usual working pistons D. The engine has the cylinder heads E for the respective cylinders forming combustion chambers F.

The cylinder block A forms with cylinders G the water jackets 10 around the outside of the cylinders for cooling. The cylinder block A is provided with inwardly extending annular projections 11, .12, each preferably being grooved to receive a sealing structure or ring 13 surrounding and contacting with the exterior wall of the cylinder G. The sealing rings 13 are preferably spaced longitudinally of the cylinder axis C to provide an annular chamber 1 1 which receives any water which might escape past the upper ring 13. The floor 15 of the lower annular projection 12 preferably inclines therefrom by the portions 16 surrounding downwardly and outwardly from the cylinder wall as at 15 so that any leakage past the upper ring 13 will be guided away from the cylinder to onev or more Outlets 17. The floor 15 preferably slopes as indicated at 18.

from the cylinder region to the outlet 17 facilitating drainage of anyleakage past ring 13.

By reason'of my invention I provide an engine of the character referred to, in which leakage of cooling water into the crank case is prevented. Thus any fluid which might leak from the water jacket 10 past the upper seal 13 will beprevented from reaching the crankcase B by. reason of the lower seal 13 spaced below the; upper seal. Furthermore as an additionalxfeature of my invention any leakage passing the upper seal and running down the cylinder walls will be guided the cylinders G and thence by reason of the sloping portions 18 of floor 15 to the various outlets17. r j

I What I claim as my invention is:

' 1. In an internal combustion engine com prising in combination, a crankcase, a cylinder block, a cylinder. separate from the cylinder block and cooperating therewith to provide acooling water jacket, and'a plurality of I sealing structures between the crankcase and water jacket said sealing structures being separated by an air chamber. j

2. In an internal combustion engine comprising in combination, a crankcase a cyl1nder. block, a cylinder separate from the cyhnder block and cooperating therewith to provide a cooling water jacket, sealing means 1 below the water jacket exteriorly of the cylinder, and additional sealing means spaced by an intermediate air chamber below the first said sealing means also extejacket, and means intermediate thecrankcase and sealing means for intercepting and draining leakage past the sealing means.

4;. In an internal combustion engine com- 5 prising in combination, a crankcase, a cylinder block, a cylinder separate from the cylinder block and cooperating therewith to provide a cooling water jacket, and upper and lower annular sealing structures surrounding the cylinder intermediate the crankcase and water jacket, the lower sealing structure having a portion sloping downwardly and. outwardly from the cylinder;

5. In an internal combustionengine comprising in combination, a crankcase, a cylinder block, a cylinder separate from the cylinder block and cooperating therewith to provide a cooling water jacket, and upper and loweranni1la.r sealing structures surround- 2'0 ing the cylinder intermediate the crankcase and water jacket, the lower sealing structure having a portion sloping downwardly and outwardly from the cylinder, said cylinder block having an opening in its wall affording escape for cooling water deflected from the cylinder by said sloping portion of the lower sealing structure.

6. In an internal'combustionengine comprising in combination, a crankcase, a cylinder b1ock,a cylinder separate iromthe cylinder block and'cooperating therewith to provide a cooling waterjacket, said cylinder "block having inwardly extending annular projections surrounding the cylinder and $5 spaced longitudinally thereof, the floor of the lower projection sloping downwardly Y and outwardly from said cylinder for' draining cooling water escaping fromthe water jacket past the upper projection.

"4 7 5 An internal combustion engine comprising in combination, a crankcase, a cylinder, a water jacket surrounding the cylinder, water jacket sealing means surrounding the cylinder intermediate the crankcase and water jacket, and a floor structure surrourid ing the cylinder intermediate the sealing means and crankcase adapted to catch leakage past the sealing means and to prevent passage of the leakage into the crankcase.

' In witness whereof, I hereunto subscribe my name this 3rd day of August, A. D. 1928.
